Was topping a tree for takedown by a service line to a house. The tree was leaning over the line so I spiked up past the point where the tree crossed the line. Used a sling and pulley so we could lower down the top without hitting the line. Made the notch, started the back cut and tried pulling over the top. Nothing. Cut a little more and all the sudden, POP, over it goes and the stem shot back so hard it knocked me and my gaffs off the wood where I found myself hanging upside down by my saddle and lanyard. Got bucked right off the thing. I'll be wiser on the leaners next time. Seems they pack an extra punch. O.K., go ahead and rip on me now. I deserve it. (Weekend hacker/slacker).
